The earliest examples of bronze vessels were unearthed in Erlitou, near the modern city of Luoyang in Henan province, which may or may not represent the earliest named Shang capital, Po, if not a still earlier Xia dynasty site. There a “palace” with pounded-earth foundation, fine jades, simple bronze vessels, and oracle bones were found. At Erligang, in the Zhengzhou area in Henan province, traces have been found of a walled city that may have been the middle Shang capital referred to as Ao.

Yin, the most enduring of Shang capital sites, lasting through the reigns of the last 9 (or 12) Shang kings, was located near the modern city of Anyang, in Henan province. Its discovery in 1899 by paleographers following the tracks of tomb robbers opened the way to verification of traditional accounts of the Shang dynasty and for the first scientific examination of China’s early civilization. There, recorded on oracle bones, the written documentation for the first time is rich, archival, and wide-ranging regarding activities of the theocratic Shang government. Excavations conducted near Anyang between 1928 and 1937 provided the initial training ground for modern Chinese archaeology and continued periodically after 1949.

No fewer than 14 royal tombs have been unearthed near Anyang, culminating in the 1976 excavation of the first major tomb to have survived intact—that of Fu Hao, who is believed to have been a consort of the Shang king Wuding and a noted military leader. The Fu Hao tomb contained more than 440 bronze vessels and 590 jade objects among its numerous exquisite works. Remains of Bronze Age settlements of the Shang period have also been found over a large area of northern and central China.

More than any other factor, it was the unearthing of magnificent bronze vessels at Anyang that demonstrated the power and wealth of the Shang rulers. The vessels were used in divinatory ceremonies for sacrificial offerings of meat, wine, and grain, primarily to the spirits of clan ancestors, especially those of the ruler and his family. They were probably kept in the ancestral hall of the clan, and, in some cases, they were buried with their owner.

Surprisingly, perhaps, the bronze vessels were not discussed in Shang oracle bone inscriptions. But by late Shang times they themselves sometimes came to bear short, cast, dedicatory inscriptions providing the name of the vessel type, the patron, and the ancestor to whom the vessel was dedicated. What may be a clan name is also often included, enclosed within an inscribed notched square of uncertain meaning but now called a yaxing. The common addition by early Zhou times (1046–256 bce) of the phrase “May sons and grandsons forever treasure and use it” provides evidence that most vessels were made originally for use in temple sacrifices rather than for burial, but other vessels, poorly cast and inscribed with posthumous ancestral names of the newly deceased, were clearly intended for the tomb.

The right to cast or possess these vessels was probably confined to the royal house itself originally but later was bestowed upon local governors set up by the ruler; still later, in the Zhou dynasty, the right was claimed by rulers of the feudal states and indeed by anyone who was rich and powerful enough to cast his own vessels.

The vessel types are known today either by names given them in Shang or Zhou times that can be identified in contemporary inscriptions, such as the li, ding, and xian (yan), or by names such as you, jia, and gong that were given to them by later Chinese scholars and antiquarians. The vessels may be grouped according to their presumed function in sacrificial rites. For cooking food, the main types are the li, a round-bodied vessel with a trilobed base extending into three hollow legs; its cousins the ding, a hemispheric vessel on three solid legs, and the fangding, a square vessel standing on four legs; and the xian, or yan, a steamer consisting of a bowl placed above a litripod, with a perforated grate between the two. For offering food, the principal vessel was the gui, a bowl placed on a ring-shaped foot, like a modern-day wok.

The word zun embraces wine containers of a variety of shapes. Among vessels for heating or offering wine are the you, a covered bucket with a swing handle; the jia, a round tripod or square quadruped with a handle on the side and raised posts with caps rising from its rim; the related jue, a smaller beaker on three legs, with an extended pouring spout in front, a pointed tail in the rear, a side handle, and posts with caps; the he, distinguished by its cylindrical pouring spout; the gong, resembling a covered gravy boat; and the elegant trumpet-mouthed gu. Vessels for ablutions include the pan, a large, shallow bowl. The shapes of the round-bodied vessels were often derived from earlier pottery forms; the square-section vessels, with flat sides generally richly decorated, are thought to derive from boxes, baskets, or containers of carved wood or bone. Other objects connected with the rites were bronze drums and bells. Weapons and fittings for chariots, harness, and other utilitarian purposes also were made of bronze.

Bronze vessels were cast not by the lost-wax process (using a wax mold), as formerly supposed, but in sectional molds, quantities of which have been found at Shang sites. In this complex process, which reflects the Chinese early mastery of the ceramic medium, a clay model of the body is built around a solid core representing the vessel’s interior; clay molding is used to encase the model, then sliced into sections and removed; the model is eliminated; the mold pieces are reconstructed around the core, using metal spacers to separate mold and core; and molten bronze is poured into the hollow space. Legs, handles, and appended sculpture are often cast separately and later integrated in a lock-on pour. Surface decoration may be added to the model surface before the mold is applied, requiring a double transfer from clay to clay to metal, or added in reverse to the mold surface after its removal from the model, with an incised design on the mold yielding a raised design on the metal surface. Ritual vessels range from about 15 cm (6 inches) to more than 130 cm (50 inches) in height with weights up to 875 kg (1,925 pounds). The intricacy and sharpness of the decoration shows that by the end of the 2nd millennium bce the art of bronze casting in China was the most advanced in the world.

While many Shang ritual bronzes are plain or only partly ornamented, others are richly decorated with a variety of geometric and zoomorphic motifs, and a small number take the form of a bird or animal. The dominating motif is the taotie, seen either as two stylized creatures juxtaposed face-to-face or as a single creature with its body splayed out on both sides of a masklike head. The term taotie first appeared in the late Zhou and is perhaps related to eclipse mythology and the idea of renewal. Song dynasty antiquarians offered the unlikely interpretation that it represented a warning against gluttony. Alternative modern suggestions are that it was a fertility symbol like the later Chinese dragon, bestowing longevity on the ruling clan; that it was a fierce spirit which protected the rites and the participants from harm; that it embodied a variety of creatures related to the ceremonial sacrifices; that it was totemic or related to shamanic empowerment; or that its dual structure represented the inseparable forces of creation and destruction. Other creatures on the bronzes are the gui (each like half of the doubled taotie), tiger, cicada, snake, owl, ram, and ox. In later times the tiger represented nature’s power, the cicada and snake symbolized regeneration, the owl was a carrier of the soul, and the ram and ox were chief animals of ancestral sacrifices. It is not known whether these meanings were attached to the creatures on Shang bronzes, for no Shang writing addresses the issue, but it seems likely that they had a more than purely decorative purpose. There is no suggested environmental setting for these creatures. The human figure appears only rarely in Shang bronzes, usually in the grasp of these powerful zoomorphic creatures.

The art of the Shang bronzes began as technically simple, albeit sometimes quite elegant, thinly cast vessels that were clearly ceramic prototypes. It reached a climax of sculpturesque monumentality at the end of the dynasty, reflecting a long period of peace and stability at Anyang. In the early 1950s the scholar Max Loehr identified five phases or styles in the evolution of Shang bronze surface decor and casting techniques. The thin-walled vessels of Style I typically carry a narrow register of zoomorphic motifs that are more abstract in appearance than motifs of later times; the motifs are composed of thin, raised lines created by incision on the production molds. Style II zoomorphic forms are composed of broad, flat bands in narrow horizontal registers, incised on the model, often on a raised band of ceramic appliqué. In Style III, dense curvilinear designs derived from those of the previous phase begin to cover much of the surface of an increasingly thick-walled vessel, and the zoomorph becomes increasingly difficult to discern. The main zoomorphic motifs of Style IV, although flush to the surface of the vessel (exclusive of appended heads, handles, and fully sculptural attachments), become clearly distinguishable as set against a dense spiral background known as “thunder pattern” (leiwen); in this phase, with similar spirals placed sparsely over the zoomorph, which itself is constructed from the same linear vocabulary, an intricate decorative system of interactive forms, rich in philosophical implications, begins to reach maturity. In Style V the main motifs are set forth in increasingly bold plastic relief through the use of ceramic appliqué upon the model. The Style I bodily form clearly reveals conceptualization derived from ceramics, while Style V vessels fully utilize the sculpturesque possibilities of the molded-bronze technology. Styles I and II appear at Zhengzhou; Style III appears at both Zhengzhou and early Anyang; and Styles IV and V are found in the Anyang period only. Pre-Style I vessels, ceramic in form, thin-walled, and with little or no surface decor, have been found at Erlitou near Luoyang, demonstrating early Shang or even Xia origins.
